Normal Temperature

Postby Pieter-Jan » Tue Nov 11, 2014 8:28 am

Hello,

I have a headless install and just connect to my board through SSH. When I monitor the Zynq temperature it's just below 70° (68-69) when the board is doing nothing. I have one of the new heatsinks. Is this normal or have I connected the heatsink wrongly?

Will I need a fan when I want to actually do something on the board?

Thanks
Pieter-Jan

Normal-ish for the idle state - without a fan. There is some variation between chips - your mileage will vary - but of course things do warm up if you actually use it!
Advice is to mount the board vertically and/or add some air-flow - even with the larger heatsinks.

See some examples here.

+1. I'd advise using a fan, but note that it needn't be at all powerful and only a small amount of airflow over the heatsink is required.

I complied xtemp.c and its running at 49 - 52 range 49 [is color blue text] and 52 [is red text]... does the 52 mean its maximum temperature recorded? i dont think it doesnt necessarily mean that I am over the recommended temperature ? or does it?

can I run this setup 24x7? 24 hours 7 days a week?

see below photo for my setup.

Red = max temp. Your results show a 'cool' Parallella - but remember that it is likely to get warmer when you use it to do actual work. Temps around 80C are considered 'hot' and best kept cooler than that.

Doing what? If running 'heavy' work (temp average of > 80C) then unlikley to last for ever. The chips are not military grade.

Novel fixing for your fans :o Some sort of paper padding? As it stands that appears to reduce air flow across the heatsinks, so perhaps you could get slightly better results without so much stuffed into the vanes.

Cheers.
